Drip water due to condensation of moisture onthe insideof the-.door or sash 6,3whenV in closed position, is directed by the top i 10,.into the gutter 17 wherein the accumu- 'facing inward and-its positiondeterminedl yvenient manner as desired ped1entA 1n practice.'

Water thus collected may be permittedtorun- .out of the ends'of theV gutter 17 or sluiceV holes such as shown at 23 may beprovided `atiintervals along thelength of theprojection .16.- `Als a lurther safeguard against entry of,water, theclosure 6 is provided with an inclined baille 'to overhang the gutter 17. In case water should get by the sealing strip 20 `:when the door or sash 6 is inV closed position, the same would be caught in a seoond gutter'26 formed between the ridge 14 ofthe base member 9 and the contiguous edge of the stop member 10. This gutter 26 will lalso trap the drip water resulting from condensation on the inside ofthe closure 6.

i rom theforeoging it will be seen thatI have provided a very simple threshold or sill 'Structurethat `is interchangeable by virtue of the reversibility of its stop abutment memf ber. Thezthreshold or'sill is further unique *in thatgno structural changes are necessary in converting it from one condition of use to the p n other, nor lare special tools requiredV in its placement. In addition to the above advantages my: invention precludes the necessity for ycarrying. in i stock separate thresholds as heretofore Y necessary for installations in whihfoppositely swinging doors or windows are specified. VIt is moreover novel in that it provides for concealment of flexible weatheringv which is retained in the structure Withnout aid of3 separate securing devices, as well Vof its 'flanges with each the closure-, said stop member being` capable ofgoffcenterrevers1ble fixture to thel ,baseA member whereby the threshold or sill is adaptedftoV either outwardly .orl inwardly opening closures, and longitudinal ridges on the ibase' member predetermining the exact oil-center postion of the stop member relative to said base-member forboth conditions ofusa` f f` i 2. -Aflthreshold orsill for swinging closures colnpromising afbase member with a mediallongitudinallridge, 'and an associate sto member of channel cross section to xd ethe ridge of thebase member, said Stopjmemberbeing' capable of location later ally olf-center to one or the other side of the medial ridge andfixture tothe base member whereby the threshold-orsill is adapted to either outwardly or inwardly opening closures.
